Item type:Publication, SELF-ASSESSMENT AMONG SKI INSTRUCTORS WITH DIFFERENT LEVELS OF BASIC ALPINE SKIING SKILLS(Science and Research Centre Koper, Slovenia, 2020); ; ; ; Kiril, NaskovSki instructors need to have adequate knowledge and skills in assessing sports techniques as a condition for successful intervention that will lead to improved performance. The purpose of this research was to assess how instructors with different levels of performance evaluate their skiing skills. A total of 58 Instructor candidates were rated with a score of 1 (lowest) to 5 (highest) by Examination Board in 7 elements of basic alpine skiing technique: Gliding straight (basic position), Wedge swinging, Wedge curves, Basic turn, Basic swinging, Wide corridor and Narrow corridor. After the practical exam, all candidates completed a self-assessment form on the same scale of 1 to 5 for each individual skiing element. The average practical grade of all seven skiing techniques, awarded by the Examination Board, was taken as a criterion for grouping. Three groups of high, intermediate and low skiing level were defined. The high performance group consisted of a total of 16 candidates with an average grade above 4. The mid-level group consisted of 26 candidates with an average grade between 3 and 4, while the low-performance group comprised 16 candidates with an average grade below 3. The results obtained from the Examination Board and the Self-Assessment were compared to determine the degree of coincidence expressed as a percentage difference between these two scores. From the results obtained, there is an evident difference in the objectivity of the self-assessment between groups. The high performance group showed the smallest percentage difference (9.79%) in the scores obtained by the Examination Board and the Selfassessment.The mid-level group showed a percentage difference between the two scores of 21.95% and the low-performance group of 54.04%. The high-performance group was recorded also by several individuals who underestimated their performances, which is not the case with the other two groups. There is a significant overrated self perception in the intermediate group and especially in the low skills group. The conclusion is that the higher level of performance increases the degree of objectivity of self-assessment. This rate of self-estimation and awareness of body position is probably due to the higher skiing experience of the candidates with the highest level of performance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Comparison of changes in the muscle strength potential of elbow flexors and extensors in adolescents following a six-week programmed exercise with modified repetitive muscle loads(Faculty for Physical Culture, University of St. Cyril and Methodius, Skopje, Republic of Macedonia, 2012)The research analyses and compares the changes of the maximum strength potential, isokinetic parameters and measures for anthropometric indicators realised in accordance with standard methods and echo sonography, between flexor muscles and extensor muscles, as well as the genetic predisposition for strength capacity development of the subjects. The experimental procedure included 21 subjects, divided into 3 experimental groups, pilot research homogenised. Individually focused programme for maximum strength capacity was realised, through exercises on Scott bench for the elbow flexor and extensor muscles during a 6-week period. The first group worked in a classic method, loading the muscle tissue along the entire elbow amplitude. The second group worked in an elbow reduced contractions methods in conditions when the muscle tissue exhibits maximum load. The third group also worked in a reduced contractions method, but in conditions when the muscle tissue can endure maximal external load. Statistical analysis showed positive effects of the experimental programme for transformation of the maximal strength capacity for both muscle parties in the three experimental groups. Data obtained from the three control points speak of similar tendency of the three experimental groups, although the subjects carried out different tasks. The elbow flexor and extensor muscle groups endured similar strength capacities transformation. The hypothesis on the association of strength capacities with the ACTN3 genotype was not confirmed from the muscle tissue genetic dominance analysis.
